Tin Pans for Complexions.
The bloom of health that glows upon the cheeks of the ladies of the chorus may be traced to the tin pans and cups that jingle on the rag-collector's wagon. These homely and prosaic vessels are made of plates of iron, coated, all too thinly in these degenerate days, with tin.
These iron plates have to be "pickled," as the trade phrase goes. All the rust and other substances than the clean iron have to be washed off with acids and water. The pickling liquor is not emptied out as slops by any means. There is a finely divided iron rust floating in it, and when the water is removed by evaporating it, the residue is Venetian red and iron pigment that, made up as rouge, can counterfeit the ruddy blood that courses so near the surface of the satin skin of youth.
It is almost a personal triumph to us to know that the broken bits of rock from the quarry, unfit to use as building material, are turned into crushed stone, for which there is so large a demand, thanks to the increasing popularity of concrete, and that its revenues pay the operating expenses of the quarry, and make the price got from building stone so much clear money.
Illuminating-gas has to be washed and scrubbed anyhow before it can be introduced into our houses. The household ammonia with which the kitchen sink is kept so sweet is taken by the thousand tons from the scrub-water of the gas-house and the furnace-gas of iron-works.
